Hi!

I have only a sample to import CSV to DBF.

Code: Select all | Expand


function mkdbf()

    if isDir(  ".\dataimport" ) = .f.
         lMKDir( ".\dataimport" )
   endif
   
   if file( ".\dataimport\import.csv") = .f.
         msginfo("Import.csv fehlt" + CRLF + "Programm wird beendet")
   endif
   
   
    if file( ".\dataimport\import.dbf") = .T.
         ferase(".\dataimport\import.dbf")
   endif

DbCreate(".\dataimport\import",;
    { {"F1", "C",   50,   0} ,;

Re: Load FROM EXCEL

Post by nageswaragunupudi »

It is extremely easy to read data of an Excel Range into an array. This is just one line code.

aData := ArrTranspose( oRange:Value ) // singe statement
Where oRange is the object of the range in the excel sheet containing the data to be read.

Example:

Code: Select all | Expand


oRange := GetExcelRange( cExcelFileName, cSheetName, { nTop, nLeft, nBottom, nRight } )
if oRange == nil
    // read failed
else
   aData := ArrTranspose( oRange:Value )
endif

XBROWSER aData
 

If we want to save aData into DBF ( assuming we have created DBF with matching structure )

Code: Select all | Expand


DBCREATE( cDbf, aStruct )
USE ( cDbf ) NEW ALIAS DST
DST->( FW_ArrayToDBF( aData ) )
CLOSE DST

   oExcel:Workbooks:Open( cFileXls ) // ABRO EL ARCHIVO SELECCIONADO
//
   oBook := oExcel:Get( "ActiveSheet" ) // ACTIVO HOJA EXCEL
   nRows := oBook:UsedRange:Rows:Count() // CANTIDAD LINEAS EXCEL INCLUYENDO LA LINEA 1 QUE ES LA CABECERA
   nCols := oBook:UsedRange:Columns:Count() // CANTIDAD COLUMNAS EXCEL

   FOR nRow = 2 TO nRows // CARGANDO DE EXCEL TABLA REPORTES
      campo :=   oBook:Cells( nRow, 1 ):Value // EL VALOR 1 ES LA COLUMNA

Si necesitas todas las columnas, la forma de Nages es super buena si quieres todas las columnas, pero que si quieres unas columnas y otras no.? lo importante es que hay opciones para usar a gusto del consumidor, saludos... :shock:

Hola,

Se puede manipular el array por ejemplo.

No iba con ningún propósito negativo, sólo reseñar que en los últimos tiempos Mr. Nages ha venido creando una serie de funciones y clases que ahorran un montón de tiempo.

Para mi, por ejemplo, TDataRow es extraordinaria en el ahorro de tiempo!.
Muchas gracias. Many thanks.

Mr. Rao
I followed his example, works well
When you exit the application and open the file with excel tells me that the file is locked read-only
I tried withlOpened: = .F. andlOpened: = .T.
Excel is running
Use Win8, office 2010
The book is formatted Excel 93-2007

He seguido su ejemplo, funciona bien
Al salir de la aplicacion y abro el fichero con excel me dice que el fichero esta bloqueado solo lectura
Excel se queda ejecutando
Uso Win8, office 2010
El libro tiene formato Excel 93-2007

After using the oRange,

Code: Select all | Expand

  oRange:WorkSheet:Parent:Close()
 

This closes the workbook.
